I don't think the 1.50 filters are Merv rated. If I'm not mistaken they are one step above the brick stopping stock ones.
The Filtrete filters restrict air flow to the coils. When replacing you can see the concave bend caused by air starvation, Not good.
The disposable ones fill up our landfills in the name of convience.
We have two (2) filters 14x20x1 I can clean them both at the same time, saving time to have more time!
Like some others here I'm retired, therefore I get paid to clean and change my filters.
God Bless America!
You really don't have to shutdown the system to change, clean the filters. You should however check the coils/fins on a regular basis or again you could restrict air flow.
The water is free the cleaners are the same ones we use to keep our Coach clean, no added cost.
The longer you use a filter the more air restriction. If you start out with lets say Merv 12 depending on dust, dirt etc. it could be pretty clogged by the time you replace them restricting air flow. which would waist more power and add more wear and tear on the equipment.
It would be great if someone had an airflow meter and did a study on this subject using different filters, the result could be eye opening!
